METHOD OF MAKING PAINT-BODIES.

- Specification of Letters Patent.

Patented Feb. 25, 1919.

Application filed January 28, 1918. Serial No. 214,129.

To all whom it may concern Be it known that I, EDWIN T. GoLnTHoRPn, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Methods of Making Paint-Bodies, of which the followin is a specification.

y invention relates to improvements in paints and method of making the same, the object of the invention being to provide an improved method for producing a paint whereby the same'may be produced from comparatively cheap materials, and whereby a highly eflicient and useful paint is provided.

The invention consists in thepaint and the method hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which, I

Figure 1 is a front 'view of a furnace shown partially in section with parts broken away for the sake of clearness,

Fig. 2, a view of the discharge end of the nace,

Fig. 3, a top plan view corresponding with Fig. 2,

furnace with portions broken away and others in section,

Fig-5, a detail view illustrating a stop 7 I been closed, the stop is manipulated to reemployed in the construction, FFlg. 6, a front view corresponding with ig. 7, a detail view illustrating a temporary stop employed in the construction, and Fig. 8, a side view corresponding with Fig. 7.

hepreferred form of construction and method of procedure comprises a furnace casing 10 having an inclined grate 1 1 therein. A plurality of fire doors 12-are provided in the front of the furnace giving-access to different portions of the grate 11 and corresponding ash doors 13 are provided thereunder, as indicated in Fig. 1. A draft flue 14 is positioned centrally over the furnace and is connected by meansof pipes 15 with branch flues 16 extending along each side of the top of the furnace. Branches 16 are connected by means of a plurality of branches'17 with the upper portion of the interior of the furnace, above the grate 11,

ig. 4, an end view of the feed end ofthe and serve to produce a draft through said I grate, the arrangement distributing said draft uniformly through said grate.

An inclined track 18 is arranged in the furnace over the grate 11 and anvertically sliding entry door 19 is positioned at the upper end of said track. A vertically sliding discharge door 20 is positioned at the lower end of said track and both ofsaid doors are balanced by counter-weights 21, as indicated. A plurality of ore containers or retorts 22, in the form of pipes, are arranged on track 18 to roll thereon, under the influence of gravity, as will be readily understood. Each of these containers or retorts is provided, at one end, with a permanent sealing cap; 23 and at its other end with a removable sealing cap 24 and having a bayonet slot connection 25 with said container. A removable swinging stop 26 is pivotally mounted in the front wall of the furnace 10 and has an upwardly turned nose 27 atits inner end arranged to be inserted between the last and the next to the last container or retort 22 resting on track 18, the arrangement being such that when the track 18 is filled with retorts, the lowermost retort rests lease the retorts on track 18 and permit said retorts to roll slightly on said track until the lowermost retort again contacts with the door 20. Then a fresh retort is introduced at the upper end of the track. By this means the operation of the furnace will be rendered continuous and the ore in the containers repeatedly agitated during the roasting thereof. i

For convenience in loading or starting the furnace, a temporary stop is provided consisting of a bar 28 having downwardly turned ends 29, said bar being adapted to be positioned on the track 18 and to prevent downward rolling of the retorts thereon. In use, a few of the retorts will. be inserted through the door 19 and held from rolling by the stop 28. After a suitable interval, the stop 28 will be moved sufficiently to permit of the insertion of more retorts and this process continued until the track 18 is filled vided on said support not free from all grit this treatment by heat and agitation, the.

adapted for use in paintin with retorts, as indicated, whereupon the stop 28 is removed.

A tiltable support 30 is arranged at the discharge end of the furnace and is pivoted at 31 to a standard 32. Clamps 33 are proa retort or container passing thereon from the tracks 18 upon elevation of the door 20. The support 30 is connected, by means of a link 3%, with a foot lever 35 by means of which the support may be readily tilted. In operation, after a container or retort has been discharged from the furnace onto the support 30 it is clamped thereon by means of the clamps 33. Then the removable cap 25 is removed and the support tilted by means of foot lever 35 to discharge the contents of the retort.

A chute 36 is arranged to receive the dis charge from a filled retort and direct the same into the spout 37 leading into a screw conveyer 38 arranged at the rear of the furnace. Conveyer 38 passes through a closed chamber-or casing 39 containing water for cooling purposes and is provided with a discharge spout 40 discharging into a discharge well 41. A suitable elevator orconveyer (not shown) may be provided for removing the roasted ore from the well 41, or said ore may be removed by hand or other suitable means.

The construction disclosed is especially adapted for the roasting of yellow ocher or oxid of iron forv usecas a body for black paint. The repeated agitation of the ore, while being roasted, tends to uniformity of heating and also prevents caking or granulation of the ore and facilitates subsequent grinding'or pulverizing of the same to such an extent as to insure the elimination of all grit or coarseness in the grinding and the production of a smooth anduniform prodor coarseness. After material is at once discharged, while still red or white hot, into where it will be suddenly cooled without the access of unlimited oxygen thereto and in the absence of-light. The yellow ocher thus treated will assume a fast and permanent black color and is ground in the usual manner with linseed oil and turpentine to form a black paint. To form such paint, preferably fifty per cent. of the ground material is mixed with forty-eight per cent. linseed oil and two per cent. of turpentine. The paint thus produced is adapted for use as a paint for all purposes, but is especially iron inasmuch as tlllie same will expand an contract therewit While I have illustrated and described the preferred method of procedure and product 4 in position to secure the cooling chamber therefrom for carrying my invention into effect, these are capable of variation and modlfication without departing from the spirit of the invention. I, therefore,='-' do not 1. The method of making a paint body which consists in roasting and agitating yellow ocher until black, substantially as described. 2.
